The construction of satisfactory roads in permafrost areas is normally more difficult than in temperate regions because the imperviousness of the underlying permafrost tends to produce poor soil drainage conditions, and because disturbance of the natural surface may set in motion adjustments in thermal regime, drainage, and slope stability which may have serious and progressive consequences. Cuts should be avoided if possible, and side slopes in fill composed of fine-grained materials should be kept to a 4 to 1 ratio or flatter. The discussion in this publication may also be applicable to design of runways in cold regions.
